Luo Xianrui (罗献瑞 Lo Hsien-shui)1, Chen Tao (陈涛)2; Michael G. Gilbert3
Climbing or twining vines, rarely erect shrubs or small trees; indumentum of simple hairs, often absent. Stems striate, without
spines; wood often with radial pith rays. Leaves alternate, spiral; stipules absent; petiole swollen at base and apex; leaf blade simple,
sometimes palmately lobed, rarely trifoliolate, venation often palmate, less often pinnate. Inflorescences axillary, sometimes from oldwood, rarely superaxillary or terminal, often umbelliform cymes, rarely reduced to single flower or flowers in a head on a discoid
receptacle, arranged in thyrses, compound umbels, or racemelike; bracts usually small, rarely leafy (female Cocculus). Flowers
unisexual (plants dioecious), usually small, inconspicuous, mostly pedicellate. Sepals often in whorls of (2 or)3(or 4), rarely reduced
to 1 (female Stephania), sometimes spirally arranged (Hypserpa, Menispermum), free or less often connate, imbricate or valvate.
Petals usually 3 or 6 in 1 or 2 whorls, rarely 2 or 4, sometimes reduced to 1 or absent, usually free, rarely connate, imbricate orvalvate. Stamens (2–)6–8(to many); filaments free or connate, sometimes stamens completely fused into synandrium; anthers 1- or 2locular or apparently 4-locular, dehiscing longitudinally or transversely. Staminodes sometimes present in female flowers. Carpels 1–
6[to many], free, often swollen on one side; style initially terminal; stigma lobed or divided, rarely entire. Ovules 2 reducing to 1 byabortion. Pistillodes very small or absent in male flower. Fruit a drupe, straight or often horseshoe-shaped; exocarp membranous orleathery; mesocarp usually fleshy; endocarp bony or sometimes woody, rarely leathery, surface usually variously ornamented, rarelysmooth, sides usually with central smooth and sunken condyle, rarely inconspicuous or lacking (e.g., Tinomiscium). Seed usually
curved; seed coat thin; endosperm present or absent; embryo mostly curved (straight in Tinomiscium); radicle small, opposite to stylescar; cotyledons flat and foliaceous or thick and semiterete.
About 65 genera and 350 species: tropical, subtropical, and few temperate regions; 19 genera and 77 species (43 endemic) in China.
Plants of the family contain many different alkaloids and are famous for their medicinal usages. Some species, such as Pericampylus glaucus
and Sinomenium acutum, are used for making rattan articles in Sichuan.

Diels recognized three species within Pycnarrhena lucida as

defined here, based largely on differences in the number of stamens andpetals. The view taken here is that this variation is continuous and,
therefore, only one species is recognized. If Diels were to be followed,
the plant in China would come closest to P. fasciculata.

More than 30 species: widely distributed in tropical and subtropical Asia to Australia and the Pacific islands (24 species), Africa (seven species),and Madagascar (two species); six species (three endemic) in China.

that they often benefit from forest clearance. These species are the larval hosts of fruit-piercing noctuid moths that cause significant damage to cropsof Citrus (particularly Mandarins) and Dimocarpus longan (Longan) in Thailand.

Two recently described species based on single collections from N
China (Menispermum chinense) and from Russia (M. miersii) differ
only in minor differences of indumentum and other small quantitative
characters and do not seem worthy of recognition.
Kundu and Guha (Adansonia n.s. 20: 225. 1998) suggested that
Menispermum mexicanum Rose is only varietally distinct from M.
dauricum.
Some collections suggest a rhizomatous rootstock.
The specific epithet is often misspelled as “dahuricum.”17. STEPHANIA Loureiro, Fl. Cochinch. 2: 598, 608. 1790.
